I guess the question is about the "general public" and everyday uses, rather than developer assistants and accelerants of the Copilot ilk.
But nevermind, since you asked about "useful" — I've as an initial skeptic and avoider nonetheless lately been thoroughly impressed with what the codeium.com/live chatbot achieves for my on-the-fly dev questions (what does X do, how to do Y, what's the prob with this Z, etc) on a certain underdocumented underblogged and under-StackOverflowed niche lang I've been just getting into. Really good to avoid flooding the actual user community itself with an endless wall of n00b Qs. Seems like actual repo grokkage is baked into it or close-enough-anyway-most-of-the-time. Hallucinations occur but seldomly and for dev stuff, anyway trivial to immediately detect or else swiftly falsify/verify. Sometimes saying "no that's not it", and another answer is proposed.
Old news here I guess, but took me a while to find a need for that sort of thing =)
